A general synthesis of a-hydroxy esters is based on 2-ethylthio-l,3-benzodithiole which serves as a methoxycarbonyl anion equivalent. Thus reaction of the lithium compound (216) with ketones followed by treatment with mercury perchlorate in methanol leads to the formation of a-hydroxy acid derivatives (217) (81SC209). 

When mercury bis[benzenetellurolate], bis[triorganophosphane]mercury perchlorate, and triorganophosphane were stirred in dichloromethane, chloroform, or acetone at 20°, cluster compounds of mercury containing tellurolate and phosphane ligands were formed2. 

Selective removal of olefins was carried out in the absorber with mercury perchlorate, which was prepared in accordance with the recommendations of Coulson [51], who used it in mass spectrometric analysis. The adsorber was prepared by treatment of refractory brick (40—60 mesh) with 1 M mercury perchlorate solution—2 Af perchloric acid (1 1, w/w) and subsequent drying at 110°C. During storage of the absorbent in a closed vessel, no decrease in its activity was observed. Rowan [50] used a layer of mercury perchlorate of height 25 cm in a copper tube of 6 mm diameter for absorption of olefins at 82 or 100 C. A layer (height 12.5 cm) of molecular sieve 4A was used to adsorb the water released from the reactor. The method of selective absorption of unsaturated compounds was used successfully for analysing petrol. 

Albert [53] developed a GC method for determining the types of hydrocarbons (aromatics, unsaturated, n-alkanes and isoalkanes) in mixtures of Cs-Cn hydrocarbons. The method is based on the use of a selective liquid stationary phase, N,N-bis(2-cyanethyl) formamide, from which aromatic hydrocarbons are eluted after the other compoimds, molecular sieves, which retain n-alkanes selectively, and an absorber containing mercury perchlorate, in which unsaturated compounds are absorbed.

Saunders studied the secondary and tertiary alkyl-carbonium ion rearrangements in superacid media by the NMR method to conclude that the intermediates in these reactions are corner- (but not ed ) protonated cyclopropanes. At the same time Lee et al. studied the trifluoroacetolysis of 1-propyl-l- C-mercury perchlor-...
